Figure 3.1. A typical database record
Analysis
After systematically characterizing the cathodes, and collecting and organizing the data, a
statistical analysis was performed to look for correlations with excess heat. To quantify the
correlation a “degree of correlation” (g) between a selected property (f) and the excess heat
occurrence (h) has been defined as:
g
f h
f
447
2
h
Where g=1 then there is full correlation between the selected property and the excess heat
production; where g=0 there is no correlation.
Results and Discussion
Figures 4.1 through 4.6 show the histograms of each of the material properties investigated in
this work, together with the indication of excess heat production (shown in the graphs with the
thinner bars).
It can be seen from these figures that some properties are well correlated with the excess heat
production. This is particularly evident in Fig. 4.2, showing that most of the samples giving
excess heat have well defined grain boundaries, while samples in which grain boundaries are
not clearly identifiable by microscope inspection, in most cases did not produce excess heat.
